CENTRIFUGAL MACHINE.

SPECIFICATION forming partV of Letters Patent No. 489,166, dated January 3', 1893. Application filed December 31, 1891. Serial No. 416,660.l (No model.) Patented in Germany 'lareh 31, 1889. No. 51,514.

To all whom it may concern: A

Be it known that I, GUsTAv PROEBER, for- 'merly of Dermbach, but now of Brunswick, in the German Empire, have invented certain new and useful improvements in centrifugal machines or l1ydro-extractors for extracting sugar-juice from crystals, and for other purposes, of which the following is aspeciication, and for which I have obtained German Patent No. 51,514, dated March 3l, 1889.

The invention consists in the construction y of centrifugal machines for separating solid substances from iluds or semi-finids, the particular feature of these machines according to the present invention being that theymay be automatically and instantaneously emptied While revolving, maintaining their regular and continued rotary motion, thereby increasing their working capability in a very simple and inexpensive manner.

In most centrifugal machines hitherto known, in which for separating purposes -the `Huid is pressed through the perforated orsievecumferential wall of such drum of anumber of parts, the latter being arranged either vertically or horizonta ly and being capable of constituting the closed drinn for the working operation, while such parts at the same time are arranged and connected with suitable mechanism for being able to be removed,

. shifted or separated from each other so as to create openings, channels or apertures for the exit of the solid substance or mass from the drum through the action of the centrifugal force. The parts, constituting the circumference of the drum may either have slanting, oblique or curved surfaces toward the center of the drum, thereby the draining surface being materially increased for the quicker or speedier removal of the fluid during the work-4 stance, but in these known machines the advance or progress or travel of the solid substances through the drum has been subject to regulation according to the nature ot' such substances, and the means for regulating such perpetual advance, progress, travel or passage of lthe solid substance lthrough the drum had t0 be adjusted individually, according to the nature of such substances.4 Such regulation has met with serious dicnlties and it is a main feature of the present invention that means have been applied, which allow after ascertaining by one or two trial operations the time necessary for each operation lo determine, watch in hand, by simply handling a lever onwheel, the duration of the centrifugal operation as regards filling, centrifuging and emptying and so on, thereby inall the consecutive operations arriving at a uniform product, as far as the dry product or solid substance separated from the fluid is concerned. The drawing represents avertical section of a machine embodying my invention. The drum may be composed of movable horizontal rings built up one over the other having angle-shaped or inclined surfaces towardthe interior of the drumas indicated in the accompanying drawing. A strong disk or plate g, rigidly connected to the vertical een tral shaft forms the lower support of the drum, said diskcarrying near its periphery several upright bolts or rods g', the upper ends of which are supported or kept, steady by aringshaped disk f. Said bolts serve as guides for the rings (l d', e c', capable of being moved in an upward ordown'ward direction. The lower ring d consisting of one incline at its inner side only, is rigidly connected to a plate a forming the bottom of the drum. This platea is connected to the above mentioned plate g (fixed to the shaft) by means of hinges and levers m m' in such a manner that byactuatngthe lever mechanism, the lower ring d and the rings e e resting ou the same may be moved in an up and downward direction. If the bottom plate a is pressed in upward direction,

be created play room or apertures betweenl the single rings. Said rings in this instance are carried by collars g2 on bolts g. The material under treatment, by t-he action of the centrifugal force will escape through said apertures. The levers m are fixed movably on the ground-plate gand they support with the other ends which are provided with anti-friction rollers, the bottom plate a of the drum. The said levers receive their mutual and parallel movement by a sleeve h which is connected to the lever m by means of levers m with links, the levers m being connected together by rods m2. Said sleeveV h is mounted 'm the vertical central shaft connected tothe latter by groove and` key, so that the sleeve will rotate with the shaft,but may be shifted vertically on the shaft np or down. Intothe circumferential groove of said sleeve the forked end of lever vh may take, said lever being pivoted on a suitable part of the framing of the machine and by moving said lever in the one or the other direction, the sleeve maybe raised or lowered at will during rotation of the shaft. .This lever h is operated by means of a rod t' con nected to its lower end. This rod has a' threaded end within a fixed nut k which is revolved by a hand-wheel Z.

The rings d e de forming the drum may be perforated and may be covered with wire gauze at the inside as usualfor allowing the liquid to escape under the centrifugal action, or they may be provided on the inclined surfaces with gutters covered by wire gauze, said -gutters `forming channels for the fluid to escape.' These channels terminate where the rings meet. It will be found preferable to unite oriflx the wire gauze to its supporting surface by means of soldering.

The drumlinay be surrounded by a mantle -fny suspended in chains with proper gear for lowering and raising said mantle. The man tle is suspended in the position' indicated on the left half of the drawing to serve as a catch for the ,fluid driven out by the centrifugal force and conducting away said fluid through the pipe which is arranged to slide according to the lowering or raising of the mantle. If said mantle is lowered andthe openings in the circumference of the drum are created by the means above indicated, the solid substance will be'thrown against the outer casing of the machine dropping into the hopper p and thus escaping into a receptacle lor wherever it is desired to lead the substance to. This arrangement may be reversed so that the movable mantle is brought into position for forming a Wall against which the solid substance is-throWn during evacuation while the said mantle is ina raised or lowered position during centrifugal action or process, the outer casing serving in such case for the catch of the fluid.

The operation with the machine is a very simple one and will easily be understeod by the foregoing specification. Y.

It is to be noted that the essential advanf tage of the machine not only consists therein that by its continuous revolving much time and power are gained, but also that by the use of inclined `parts protruding toward the innerv space of the drum, the draining surface of such drums is essentially increased in View of ,the old drums of equal diameter.

Vhat l claim as my invention and desire to secure by Letters Patent is:

1. In a centrifugal machine, a rotary een'- tral shaft, horizontal rings concentrieally surrounding the shaft and movable toward and away from each other tofform the sides of a closed or open drum, a plate a forming the bottom of said drum Aand having a sliding movement on the shaft, a bed plate g rigidly afxed to the shaft, levers carried by said bed plate and lengagingthe said plate a, a movable boss sliding on said shaft and connected to the levers for raising and lowering Y YYtheplate a andthereby the/horizontal rings,n Y

and means for shifting the movable boss up and down on the shaft, substantially as and for the purpose hereinbefore set forth.

2. T he`combination ina centrifugal niaehine of a rotary central shaft, a hub thereon, horizontalrings e, e surrounding the said` shaft and hub, a bed plateg rigidly affixed to the lower end of the said hub, an annular diskf, rods g affixed to the said plate g and disk fto guide the rings e, e', and having eollars g2, g2 for the support of said rings e, e', a bottom plate a. capable of sliding on the said hub and levers m', m,m2 between said plates g and a for the purpose of controlling the said plate a and rings e, e to open and close annular spaces formed between them and the said diskf, substantially as and for the purpose hereinbefore set forth.`

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
